Application led December 12, 1916. l Serial No. 136,449.

To all 'whom t may concern simultaneously, constitutes still another ob- Be it known that I,ALFRED W. KNUTsoN, acitizen of the United States, and a resident of Galesburg", in the county of- Knox and State of Illinois, have in vented a new and useful Stop Device for Stalls, of whichthe following is a specification.

My invention relatesin general-to cattlestalls Aequipped with stanchions. In the present-day type of stall some 'sort of de-V vice is provided whereby to so obstruct lthe space between the suspended member of the stanchion and the adjacent stall-post that the animal is practically forced to insert its head'between the stanchion members, and the principal object of the invention, broadly stated, isto improve the construction and increase the utilityy and efficiency of devices of this nature.` Y

,IVhen the relatively movable. arm of a stanchionV swings open its gravitywill incline the lower end ofthe fixed 4arm in the opposite direction, if the stanchion be capablev of laterally swinginginovement. To provide .a guard or,A as it is known tothe trade, a sure-stop which when in `operative position will `conform in inclination to said fixed stanchion arm, whereby to more, effectively fill the space between said arm and the adjacent stall-post, constitutes a special object. Y Y 1 To so construct the sure-stop bar or tube that its lower end turns on a stud while its upper end moves cycloidally, constitutes another object.

To providefor connecting togetherl a -plurality Vof Sure-stop or` guard-bars (one in each stall) whereby they may be operated ject. l

To provide' a novel footv for the; guardbar is an object. 1

It is Van object to so lconstruct the guardbar and thev means foroperating it that when the animal is confined between the stanchion-arms thefbar may beswungv out ofthe way, wherebyY to permit the animal to Y lfreelyswing its head from side to side, in

order to lickitself, etc. Y l',Io dispense with links, couplings or the like, arranged closeto and parallel with the floor, constitutes, an object, for these catch on the bedding and litter andV frequently failto operate.

To equip a series of stalls with Sure-stops which 'are so frictionless in operationthat a large number. thereof may be operated with- VSpeciicaton of Lettersratent. Patented Aug. "7, 191

out'the aid of levers or other power-increase ing means, 'constitutes 'another of` thelob-A jects.A K -1 A To arrange the connecting and manipu. lating raill directly-r above the stall-frame rail Y(1),- forpurposes later herein described, constitutes stillanother object. Y. Y Toso construct the coacting means which operate the Lsure-stopsthat it. ieg-practically impossible for va novice to place them in 'wrong positions relatively to the stop, is an object` .V

Numerous minor objects, some of which will be obvious andothers of which will be specifically pointed out, will presently ap.

wpear.

The nature of the invention isfs'uicli that It-.will-,be readily understood by referenceto the accompanying drawings and to vthe followingv specification, but it Vmust be under'stood thatV ,Saidvr drawings and descrip'.- tion disclosel only that particular embodi-v ment vwhich I at present prefer and which hasrproven, -in operation, to be practical,

ellicient and successful, and that the details arev subject to muchmodification without departing from the 4 principles and novel features .of the invention defined in the claims, in which claims it is myinte'ntio'n to claim as broadly-as is permitted by the Statel of the art, allthe novelty inherent' in the invention. In said drawings: Y

VFigure 1 is alfront elevation showing one complete stall and` the sure-top or guard bar of an adjacent one;

VFig. 2, an` enlarged ,detail ofthe upper portion of thel sure-stop, the mechanism for operating it,l andother-portions of the stall; .Fig. 3, `an enlarged sectional detailits planetaken in the line 3- 3 in Fig. 1; and f Fig. 4, a transverse section, taken inthe line 4 4 in Fig. 1, most of the-"parts shown in endelevation. l

VConsideringfthe `drawings in detail and` referring` to the-elements and', where necessary', each by a distinguishing numeral, uni-v formly employech 1 designates the usualvv stanchionesupporting rail; 2 the'stall-floor; a stanchion-head Securedtothe rail l; 4

ics

coacting .stanchion-arm hinged at its lower end to the arm 4 andits upper end adapted forengagement with the head 3;l 6', ayoke swiveled in the Hoor 2; 7, a chain connecting the stanchion-arms therewith; and 8, 8,

stall-posts secured at their lower ends by clips 9, 9, bolts 10 and nuts 10 to the floor 2 and at their upper ends secured by bolts 11 and nuts 12 to clips 13, 13 secured by bolts 14 and nuts 15 to thek rail 1. I make no claim herein to any of these elements per se.

,G My improved sure-stop orguide-bar'lG is preferably made of tubular metal and comprises a centrally arranged body portion 17 having an offset upper portion 18 and a similarl-y oifset flower portion 19. vPreferlb ably the axes of the portions 18 and 19 are linea'lly arranged, and preferably the axes of the portions 17, 18 and 19 are substantially parallel. By thus offsetting the upper and lower ends from the-median portion (or 2g vice versa) the latter becomes a crank-arm whereby the sure-stop or bar may be -roy tated. 20 designates a rfoot secured -rigidly to the vfloor 2 and clips 10 by means of a bolt 21 and nut 22. VIt is provided with a 25 swivel-stud 23 on which seats` the lower end of the guide-bar., The Aupper end of the bar isqxed by means of a hubf24 and pin 24 to an actuating pinion 25.

' 26 indicates a stationary rack having two oftits teeth spaced farther from each other than are the others, as shown -at 27 in order Vto receive in the greater' space one enlarged tooth, 28, on the pinion 25. One terminal, 30, of said rack is securedA by one ofthe bolts 11 to the clip 13 vand itsv other terminal", 31, is projected upward, at a right angle to the vrack-body, and has a groove in which onefcorner of the rail 1 seats. Secured to the projection 31 by a bolt 32 and nut a@ 33 is a clip 34 wherebv said rack is held rigidly upon the rail -1.

35 designates a sliding rack two teeth of which are spaced farther apart than are the others, as shown at 36. It has an upwardly ra extending arm A35 which is recessed at 37 to tit lover a corner of the rail 1 and has also asemicircular recess 38 which fits over o ne side of a combined connecting and manipulating rail 39 which `may extend over Aone 5@ or Aa plurality of stalls, as may be necessary or desired. 40 indicates an arm or bracket having a recess 41 which coacts with the recess 37, fitting over the opposite side ofthe rail 1. By `means of bolts 42 and nuts 43 the members 35 and 4 0 rare held securely together, but in ksuch manner that the portions 37 and 4.1 may slide freely upon the 'rail 1. vrThe arm 40 'is provided also with a recess 44 which coacts with the recess 38, tting over the opposite side of the rail 39. The bolts 42 and nuts 43 bindy the recessed parts 38 and 44 closely upon the rail, `39, whereby lmovement of said rra-il will Amove the rack 35 and Avice versa.

35 Iny orderthat the su're-stop-bar be so positioned that when the sta-nchion arms are opened its body portion will lie substantially parallel with the arm 4, as shown clearly by full l'inesin Fig. 1, and that when the stanchion arms are closed it will lie close to and substantially parallel with the adjacent stall-post 8, as shown by the dotted lines in said figure, I have provided theindicating tooth 28 on the vpinion 25, which tooth is to be positioned in the space 27 in 75 the 'rack 26 the lower-end of the stop 16 having been placed overv the pivot stud 23 and its upper end secured -to the pinion. The stop -is then turned to the position shown by dotted lines in F l and the tooth 28 positioned in the space 36, whereupon the several securing bolts and nuts are nto be drawn up taut. The operator may operate the stop b v means of either the lrai-l 39 or lby tu'rningthe bar itself, and it 85 will be evident that when movement is imparted to either it will be transmitted to all the stops connected with the said rail. It is to be noted that no levers or other lpowern increasing elements are shown, for the fric- 9a tion of the moving parts is so minute that none are required, and the operator does not have to walk to a lever, but may grasp the rail 39 at any point along its `length to thereby .operate it, or he may, of course, operate that one `of the lstops nearest lhim and thereby operate all.

Also it iis -to Ebe noted that the operatin rail is placed directly above vthe stall-rai. llhus positioned not only is it extremely convenient of access but also it is not in the way either of the stab'l'eman lor the animal,

The direction of movement of the diagonal portici/1.50 of the stop 16 is shown clearly 105 by the dotted line a in Fig. 3, which shows it to move ina cycloidal manner. The foot of the stop rotates on the stud 23, and its head simultaneously yrotates and moves laterally. The described manner of 4rotating 110 the-'lower end of the` stop on la stud I have found to -be `a Avery superior one, for there are no projecting arms or :brackets which catch inthe bedding and ythusfail to operate, or at least to operate freely and eiiectively, and' which are liable to breakage `by reason of the cattle stepping on that end which is elevated from-the floor. By rotating the upper andv lower terminals of the stop and moving the former sidewlise the stop will substantially parallel the inclined arm 4, and thus more completely close the gap between it and the post when the stanchion is opened, and will lie substantially parallel with `thesta-l'hpost when the stanchion arms 125 are closed, whereby to give `the animal freedom `of movement of its head. ItY will be clear also that the fact that the end portions of the stop are offset fromits Ibody or central kportion permits it to lie closer to the'opened stanchion, when desired, and

to the stall-post when desired, than it would if it were free from bends. l

`The parts comprising my improvement maybe sold as an attachment to a previouslv built stall of the nature disclosed,

for the rod 89,-the stop 16 and its operating parts, and the foot 20 may be attached, in an evident manner, by `means of only the bolts land nuts 111-15, 32-38, and 4t2-4 3, tothe previously set stall-members.
